In 2020, the highest rates of cervical cancer incidence and mortality were reported in Asian and African regions of the world. Across the globe, growing evidence confirms cancer disparities among racial and ethnic minorities, low socioeconomic status groups, sexual and gender minorities, uninsured individuals, and rural residents. Recognition of these stark disparities has led to increased global efforts for improving screening rates overall and, in medically underserved populations, highlighting the urgent need for research to inform the successful implementation of cervical cancer screening. Implementation science, defined as the study of methods to promote the integration of research evidence into health care practice, is well-suited to address this challenge. With a multilevel, implementation focus, we present key research directions that can help address cancer disparities in resource-limited settings. First, we describe several global feasibility studies that acknowledge the effectiveness of self-sampling as a strategy to improve screening coverage. Second, we highlight Project ECHO as a strategy to improve providers' knowledge through an extended virtual learning community, thereby building capacity for health care settings to deliver screening. Third, we consider community health workers, who are a cornerstone of implementing public health interventions in global communities. Finally, we see tremendous learning opportunities that use contextually relevant strategies to advance the science of community engagement and adaptations that could further enhance the uptake of screening in resource-limited settings. These opportunities provide future directions for bidirectional exchange of knowledge between local and global resource-limited settings to advance implementation science and address disparities.

Background & objectives: Lack of awareness is one of the major reasons for the high morbidity and mortality associated with cancers. The present study was aimed to evaluate the awareness of prevalent cancers among the rural population in a district of north India and its association specifically with mobile phone usage. Methods: Using a stratified random sampling technique, households in three villages of Gautam Buddh Nagar district of India were selected. A house-to-house survey on cancer awareness was conducted among adults in selected households and data were analyzed to check for the association of such an awareness with sociodemographic factors and internet usage. Results: The study included 59 males and 145 females, with majority (115) being in the age group of 18-30 yr. Although most (96.5%) of the participants were aware of cancer, the common risk factors and warning signs of cancer were known to only a few. Specific risk factors for cervical and breast cancers were, however, not known to a majority (79.9% and 72.2%). A significant association between the awareness of general risk factors and warning signs as well as specific aspects including risk factors for breast, cervical and oral cancer, HPV vaccine and the education level of the participants (P<0.05 for all). Knowledge of risk factors, warning signs and cancer prevention modalities was higher among mobile phone users who accessed internet for health information. There was no significant association between age group and cancer risk factor awareness, though females were more aware of the risk factors for breast cancer (P=0.002). Interpretation & conclusions: The findings of this study highlight the existing low level of awareness of cervical and breast cancers among the rural population. The association of cancer awareness with education level and mobile phone-based internet usage suggests the potential utility of internet-based platforms such as m-health programmes for cancer prevention activities.

Cytology identifies the women who are at higher risk of harboring high-grade cervical premalignant lesions or invasive cancer. However, a diagnostic test such as colposcopy is crucial for women with abnormal cytology for localization of the abnormality, confirmation of diagnosis, and appropriate management. To standardize this subjective technique and to minimize the interobserver variations, Swede scoring system was introduced. The revised colposcopic nomenclature of the International Federation of Cervical Pathology and Colposcopy in 2011 included various normal and abnormal colposcopic findings and gives a description of colposcopic features which improves its accuracy over the colposcopic indices. There is consensus agreement that cytology indicative of high-grade lesions (ASC-H and HSIL in the Bethesda system) should engender immediate referral for colposcopy and biopsy. The management of women who have equivocal or borderline cytology of low-grade abnormalities (ASCUS/LSIL) is still under deliberation. It is generally agreed to have an HPV triage for women with equivocal cytology. Based on the latest recommendations, the current chapter provides an extensive overview of the role of colposcopy in the management of women with various abnormalities reported on Pap smear.

Introduction: Nurses are the foundation of the Indian health system. They play a crucial role in primary care and implementation of community-centered government health initiatives such as cancer screening. The purpose of this manuscript is to share the experience of this educational intervention study and emphasize the need for drastic medical education reforms to include curricula to strengthen knowledge about cancer screening among nursing students. Methods: A one-day workshop on "Cervical and breast cancer screening" was conducted for nursing students pursuing BSc Nursing (Group 1) and General Nursing and Midwifery (GNM) (Group 2) in India. A structured, self-administered questionnaire was administered among consented participants before and after the workshop to assess their knowledge and awareness on the subject at the baseline and the improvement they gained after the workshop. Results: Ninety-one students attempted both pre and post-surveys, of which 56 were from Group 1 and 35 from Group 2. Students demonstrated statistically significant improvements in knowledge on cervical and breast cancer screening after participating in the workshop. Conclusion: Undergraduate nursing education curricula must undergo medical education reform to include education and training for nurses in cancer screening and further motivate their increased participation in preventive cancer screening programs.

Objective: To assess the impact of recently published American Society of Cytopathology (ASC) guidelines (2017) on the conduct of cervical cytology‐histology correlation (CHC). Methods: A retrospective review was conducted for cervical biopsies with their corresponding conventional cervical smears over a 7.5‐year period (January 2011‐June 2018). As per the ASC guidelines, a discrepancy assessment grid was prepared. Major cytology‐histology discordance was defined as a diagnosis of high‐grade squamous intraepithelial lesion (HSIL) or CIN2+ in one of the tests with negative result in the other. Smears and biopsies of all discordant cases were reviewed for reasons of overcall and undercall. Results: Of the 341 cervical biopsies with corresponding Papanicolaou smear, cytology‐histology agreement was noted in 249 (73%) cases. Major discordance was observed in 22 cases (6.4%)—16 undercalls and six overcalls on cytology—while minor discrepancies were noted in 70 cases. Atypical metaplasia and repair changes were the main reasons for overcall while small HSIL cells in atrophic smear and scant HSIL cells were important causes of undercall on cytology review. Using the ASC guidelines, we could improvise upon the existing CHC methodology for categorisation of cyto‐histological pairs of cases with a cytological diagnosis of atypical glandular cells. Conclusion: The present study demonstrates, for the first time, that the recent ASC guidelines facilitate cervical CHC, especially for categorisation of cases with atypical glandular cells on cytology. Uniform application of these guidelines would standardise the conduct of cervical CHC internationally and provide scope for inter‐laboratory comparison of data as well as enhance self‐learning and peer learning. The current American Society of Cytoapthology's guidelines could facilitate the uniform conduct of cyto‐histologic correlation in laboratories engaged in cervical pathology and provide scope for inter‐laboratory data comparisons.

Objective To find an association between metabolic non-communicable disease (NCD) risk factors (high blood pressure (BP), high random blood sugar (RBS) and overweight/obesity) and oral, breast, cervical cancers/precancerous or potentially malignant conditions. Design This is an observational study using convenience sampling. The participants were screened through opportunistic or population-based screening. Setting The study was conducted at a health promotion clinic (HPC) located in Northern India under the Indian Council of Medical Research. HPC is a screening clinic where screening is done for hypertension (HT), diabetes mellitus (DM), obesity, and oral, breast and cervical cancers. The study was conducted between December 2016 and January 2019. Participant The number of participants screened was 8352 (6712 women and 1640 men). All consenting men and women above 18 years were included. All participants were screened for oral cancer, DM, HT and obesity. All women were also screened for breast and cervical cancers. Cervical screening was done for non-pregnant women 21 years and above with history of sexual activity. Result Oral potentially malignant disease (OPMD) was the most prevalent, followed by breast cancer, oral cancer, cervical cancer and cervical precancer. High RBS had a strong association with oral cancer (OR=2.29, 95% CI 1.09 to 4.82, p=0.03) and breast cancer (OR=1.95, 95% CI 1.01 to 3.76, p=0.05). High BP had a strong association with breast cancer (OR=2.50, 95% CI 1.43 to 4.35, p<0.0001). An inverse association was noted between oral cancer and overweight/obesity (OR=0.20, 95% CI 0.08 to 0.48, p<0.0001). Current tobacco use was strongly associated with oral cancer (OR=6.51, 95% CI 3.63 to 11.67, p<0.0001) and OPMD (OR=9.82, 95% CI 8.13 to 11.86, p<0.0001). No association was elicited between the metabolic NCD risk factors and cervical cancer/precancer. Conclusions The study reaffirms that NCD metabolic risk factors determine oral and breast cancers. Besides NCD risk factors, current tobacco use was a strong determinant of OPMD and oral cancer. Hence, primary and primordial prevention measures to control NCD metabolic risk factors and tobacco use should move along with secondary prevention of breast and oral cancers. [ABSTRACT FROM AUTHOR]

Purpose: To address high breast cancer (BC) mortality globally and especially in low- and middle-income countries (LMICs), resource-stratified screening and treatment guidelines have been provided by global expert groups. How these guidelines are implemented and aligned with facility readiness in low-resource settings is less well understood. We propose to modify, apply, and evaluate a cervical cancer toolkit designed to evaluate facility readiness in LMICs as an implementation science tool for the treatment of BC. Methods: We will draw upon an existing toolkit for cervical cancer, the Improving Data for Decision Making in Global Cervical Cancer Programs (IDCCP) developed by the Centers for Disease Control and Prevention, WHO, and the George W. Bush Institute. The IDCCP includes 13 domains—for example, services, staffing, infrastructure, procurement and supply chain, equipment and supplies, referral pathways, etc—by which to assess facility readiness, and information on six categories is available in India's District Level Household and Facility Level Survey (2012 to 2013). We applied the IDCCP toolkit for cervical cancer screening in India using District Level Household and Facility Level Survey data and propose to extend this work to include BC screening evaluation per Indian government guidelines—clinical breast exam followed by ultrasound, with or without mammography, followed by biopsy as needed across the four tiers of India's public health care system. As a test of construct validation, we will correlate facility readiness for BC screening at the district level with self-reported BC examination data at the district level using the National Family Health Survey-4 (2015 to 2016). Results: Composite scores that summarize the six categories for cervical cancer yield wide variation in facility readiness across 30 states and union territories, with a trend toward higher scores for higher levels of the public health care system. Some consistencies emerge for higher-performing states, such as Maharashtra and Goa. We will conduct similar analyses for BC screening after modifying the tool kit for BC. Conclusion: The modified toolkit for either BC alone or in combination with cervical cancer can be considered an implementation science tool to by which assess facility readiness of health centers in LMICs and for understanding gaps in the implementation of government guidelines.

Objective: To compare the AV Magnivisualizer with colposcopy to detect cervical intraepithelial neoplasia (CIN) using the Swede scoring system.Methods: Cross-sectional study conducted in a tertiary care hospital from May 2017 to March 2018. One hundred women with positive results at visual inspection with acetic acid underwent cervical inspection using the Magnivisualizer followed by a colposcope. Biopsies were taken if the Swede score was greater than 4. Pregnant women, women with an obvious cervical growth, acute cervicitis, or prior cervical surgery were excluded. Diagnostic accuracy of the Magnivisualizer and colposcope was calculated for high-grade lesions (CIN 2/CIN 2+) and agreement was compared between the two modalities.Results: The sensitivity, specificity, and positive and negative predictive values of the Magnivisualizer were 88.2%, 70.0%, 50.0%, and 94.6%, respectively, to detect high-grade lesions at a Swede score cutoff of 5 or more. The area under the curve for the Magnivisualizer was 0.80 (95% CI, 0.67-0.92), which was comparable with colposcopy (AUC 0.86; 95% CI, 0.76-0.96). There was very good agreement between the Magnivisualizer and colposcopy (κ=0.865, P<0.001) for high-grade lesions.Conclusion: The Magnivisualizer had high diagnostic accuracy to detect high-grade CIN in screen-positive women, which was comparable with colposcopy.

The article focuses on the use of human papillomavirus vaccine for preventing cancer cervix in India. Topics discussed include improving public health in the country; analysis of immunogenicity, adverse effects and cost-effectiveness of the vaccine; and World Health Organization's recommendations on the same.

Management algorithms for screen-positive women in cervical cancer prevention programs have undergone substantial changes in recent years. The WHO strongly recommends human papillomavirus (HPV) testing for primary screening, if affordable, or if not, then visual inspection with acetic acid (VIA), and promotes treatment directly following screening through the screen-and-treat approach (one or two clinic visits). While VIA-positive women can be offered immediate ablative treatment based on certain eligibility criteria, HPV-positive women need to undergo subsequent VIA to determine their eligibility. Simpler ablative methods of treatment such as cryotherapy and thermal coagulation have been demonstrated to be effective and to have excellent safety profiles, and these have become integral parts of new management algorithms. The challenges faced by low-resource countries are many and include, from the management perspective, identifying an affordable point-of-care HPV detection test, minimizing over-treatment, and installing an effective information system to ensure high compliance to treatment and follow-up.

India's cervical cancer screening program was launched in 2016. We evaluated baseline facility readiness using nationally representative data from the 2012-13 District Level Household and Facility Survey on 4 tiers of the public health care system - 18,367 sub-health centres (SHCs), 8540 primary health centres (PHCs), 4810 community health centres and 1540 district/sub-divisional hospitals. To evaluate facility readiness we used the Improving Data for Decision Making in Global Cervical Cancer Programmes toolkit on six domains - potential staffing, infrastructure, equipment and supplies, infection prevention, medicines and laboratory testing, and data management. Composite scores were created by summing responses within domains, standardizing scores across domains at each facility level, and averaging across districts/states. Overall, readiness scores were low for cervical cancer screening. At SHCs, the lowest scores were observed in 'infrastructure' (0.55) and 'infection prevention' (0.44), while PHCs had low 'potential staffing' scores (0.50) due to limited manpower to diagnose and treat (cryotherapy) potential cases. Scores were higher for tiers conducting diagnostic work-up and treatment/referral. The highest scores were in 'potential staffing' except for PHCs, while the lowest scores were in 'infection & prevention' and 'medicines and laboratory'. Goa and Maharashtra were consistently among the top 5 ranking states for readiness. Substantial heterogeneity in facility readiness for cervical cancer screening spans states and tiers of India's public healthcare system. Infrastructure and staffing are large barriers to screening at PHCs, which are crucial for referral of high-risk patients. Our results suggest focus areas in cervical cancer screening at the district level for policy makers. [ABSTRACT FROM AUTHOR]

Cumulatively, breast, cervical, ovarian, and uterine cancer account for more than 70% of cancers in women in India. Distinct differences in the clinical presentation of women with cancer suggest underlying differences in cancer biology and genetics. The peak age of onset of breast and ovarian cancer appears to be a decade earlier in India (age 45-50 years) than in high-income countries (age >60 years). Understanding these differences through research to develop diagnosis, screening, prevention, and treatment frameworks that ar e specific to the Indian population are critical and essential to improving women's health in India. Since the sequencing of the human genome in 2001, applications of advanced technologies, such as massively parallel sequencing, have transformed the understanding of the genetic and environmental drivers of cancer. How can advanced technologies be harnessed to provide health-care solutions at a scale and to a budget suitable for a country of 1·2 billion people? What research programmes are necessary to answer questions specific to India, and to build capacity for innovative solutions using these technologies? In order to answer these questions, we convened a workshop with key stakeholders to address these issues. In this Series paper, we highlight challenges in tackling the growing cancer burden in India, discuss ongoing genomics research and developments in infrastructure, and suggest key priorities for future research in cancer in India.
